The Pic du Midi de Bigorre or simply the Pic du Midi (elevation 2,877 m (9,439 ft)) is a mountain in the French Pyrenees. It is the site of the Pic du Midi Observatory.

The Pic du Midi Observatory (
Construction of the observatory began in 1878 under the auspices of the
A 1.06-meter (42-inch) telescope was installed in 1963, funded by NASA and was used to take detailed photographs of the surface of the Moon in preparation for the Apollo missions. In 1965 the astronomers Pierre and Janine Connes were able to formulate a detailed analysis of the composition of the atmospheres on Mars and Venus, based on the infrared spectra gathered from these planets. The results showed atmospheres in chemical equilibrium. This served as a basis for James Lovelock, a scientist working for the Jet Propulsion Laboratory in California, to predict that those planets had no life - a fact that would be proven and scientifically accepted years after.[6]
A 2-meter telescope, known as the Bernard Lyot Telescope was placed at the observatory in 1980 on top of a 28-meter column built off to the side to avoid wind turbulence affecting the seeing of the other telescopes. It is the largest telescope in France. The observatory also has a coronagraph, which is used to study the solar corona. A 0.60-meter telescope (the Gentilly's T60 telescope) is also located at the top of Pic du Midi. Since 1982 this T60 is dedicated to amateur astronomy and managed by a group of amateurs, called association T60.[6]
The observatory consists of:
- The 0.55-meter telescope (Robley Dome);
- The 0.60-meter telescope (T60 Dome, welcoming amateur astronomers via the Association T60);
- The 1.06-meter telescope (Gentilli Dome) dedicated to observations of the solar system;
- The 2-meter telescope or Bernard Lyot Telescope (used with a new generation stellar spectropolarimeter);
- The coronagraph HACO-CLIMSO (studies of the solar corona);
- The bezel Jean Rösch (studies of the solar surface)
- The Charvin dome, which sheltered a photoelectric coronometer (which studied the Sun);
- The Baillaud dome, reassigned to the museum in 2000 and which houses a 1:1 scale model coronagraph.
The observatory is located very close to the
Saturn's moon

International Dark Sky Reserve
Officially initiated in 2009, during the international year of astronomy, the Pic du Midi International Dark Sky Reserve (IDSR) was labeled in 2013 by the
The IDSR aims to limit the exponential propagation of light pollution, in order to preserve the quality of the night. Co-managed by the Syndicat mixte for the tourist promotion of the Pic du Midi,[10] the Pyrénées National Park[11] and the Departmental Energy Union 65,[12] its priority actions are the public education on the impacts and consequences of these pollutions as well as the establishment of responsible lighting in the Haut-Pyrenean territory.
It covers 3,000 km2, or 65% of the Hautes-Pyrénées. The IDSR includes 251 communes spread around the Pic du Midi de Bigorre and is distinguished in two zones:
- A core zone, devoid of any permanent lighting and witnessing an exceptional night quality;
- A buffer zone, in which the territory actors recognize the importance of the nocturnal environment and undertake to protect it.
The IDSR initiated the program "Ciel Etoilé" (Starry sky),[13] program of reconversion of the 40 000 luminous points of its territory, the program "Gardiens des Etoiles" (Guardians of the stars),[14] program of metrological monitoring of the light pollution evolution, but also the program "Adap'Ter", project that will identify "trames sombres" (Dark frame: nocturnal biodiversity deplacements).[15]
